Retirement planning for salaried professionals in India: corpus math, NPS, EPF and the bucket strategy

Retirement planning in India gets talked about in two unhelpful ways. One camp says "just invest in NPS and relax." The other says "you need Rs 10 crore minimum." Neither is useful. The first ignores how much income you actually need; the second ignores how different two Rs 10 crore corpuses can be depending on what they are invested in and how they are drawn down.

This article walks through what the corpus number actually depends on, why the famous 25x annual expense rule from US retirement literature understates things for Indian professionals, how to combine EPF, NPS and voluntary SIPs into one coherent plan, and the four-bucket drawdown structure that keeps a retired household calm through every market cycle.

What "retired" actually means financially

Retirement is the day your household stops earning employment income and starts living entirely off accumulated assets. In numbers, two things change simultaneously on that day:

• Monthly inflow from salary stops.
• Monthly outflow for household expenses continues, adjusted for whichever lifestyle changes (fewer commute costs, maybe more travel, maybe more medical).

The question retirement planning answers: how much accumulated capital is needed, invested how, so that the outflow can continue safely for 25 to 35 years? Longer than most people think.

Why the "25x annual expenses" rule understates it in India

The famous American rule is: multiply your current annual expenses by 25, invest the corpus in a 60/40 equity/bond portfolio, withdraw 4 percent of the starting value each year, and the portfolio statistically lasts 30 years.

It is a useful starting point. It understates the Indian number for three reasons.

One: inflation is higher. US long-term inflation is around 2.5 percent; India's is 5 to 7 percent. The 4 percent withdrawal rule is derived from US inflation. Indian conservative withdrawal rates sit closer to 3 to 3.5 percent, which means the multiplier is 28 to 33, not 25.

Two: healthcare costs grow faster than CPI. Indian medical inflation has run at 12 to 14 percent for a decade. A health insurance premium that costs Rs 60,000 today may cost Rs 2.5 lakh in 15 years. A conservative plan builds in a separate healthcare provision rather than assuming CPI inflation covers it.

Three: life expectancy has quietly risen. A healthy Indian professional retiring at 60 today has a 40 percent chance of one spouse living past 90. That is 30+ years of drawdown. The 25x rule was built around 25-year retirements.

Realistic Indian corpus multipliers:

• Retire at 58, comfortable lifestyle: 30 to 33x annual expenses
• Retire at 60, moderate lifestyle: 28 to 30x annual expenses
• Retire at 60, with separate medical corpus: 25 to 27x annual expenses plus medical corpus
• Retire at 65, modest lifestyle: 22 to 25x annual expenses

A worked example

Professional, age 42, current monthly household expenses Rs 1.5 lakh (Rs 18 lakh per year). Plans to retire at 60. Expects post-retirement lifestyle to stay similar in today's rupees.

Step 1 — inflate current expenses to the retirement year. At 6 percent inflation for 18 years, Rs 18 lakh grows to approximately Rs 51 lakh per year at age 60.

Step 2 — apply the multiplier. Using 30x as a balanced Indian multiplier: Rs 51 lakh × 30 = Rs 15.3 crore needed at age 60.

Step 3 — work backwards to monthly SIP. Assuming an 11 percent CAGR on long-term equity (conservative), a Rs 15.3 crore corpus in 18 years needs an SIP of roughly Rs 1.9 lakh per month, flat. With a 10 percent annual step-up (raise the SIP each April with your salary), the starting SIP drops to around Rs 95,000 per month.

Most salaried households in this profile are doing Rs 40,000 to Rs 70,000 per month in SIPs and EPF combined. The gap is real. Closing it requires either a higher SIP, a step-up rule, or accepting a later retirement date.

How EPF, NPS and voluntary investing fit together

EPF (Employees' Provident Fund).
Mandatory for most salaried employees. Current interest rate 8.25 percent, tax-free at maturity (if held 5+ years and on retirement). For most professionals, EPF contribution plus employer match comes to around 24 percent of basic salary. Over 25 to 30 years, EPF alone typically builds to Rs 1 to Rs 3 crore. Useful foundation, not sufficient by itself.

NPS (National Pension System).
Voluntary contribution up to Rs 50,000 extra deduction under Section 80CCD(1B) over and above the Rs 1.5 lakh Section 80C limit. Returns depend on your asset allocation choice (Equity, Corporate Debt, Government Securities, Alternatives). Equity in NPS is capped at 75 percent until age 50, then steps down. Taxation at exit: 60 percent of corpus is tax-free, 40 percent must go into annuity which is then taxed as income. Useful for the tax deduction and the forced long-term equity allocation, but the mandatory annuity portion limits flexibility.

Voluntary equity SIPs via mutual funds.
The workhorse. More flexible than EPF (you can pause, increase, redeem), higher expected return than NPS (no equity cap), fully liquid, taxed favourably (12.5 percent LTCG on gains above Rs 1.25 lakh per year). Should be the largest leg of any retirement plan for a professional under 50.

A reasonable combined structure for a 35 to 45-year-old professional:

• EPF — whatever is mandatory (not a choice)
• NPS — Rs 50,000 per year under 80CCD(1B) for the tax benefit
• Voluntary SIPs — fills the rest of the required monthly investment, mostly in large-cap and flexi-cap equity funds, step-up 10 percent annually

By age 55, start shifting a portion of SIPs into hybrid or balanced advantage funds to begin dialling down equity exposure.

The four-bucket drawdown strategy

Accumulation is only half the story. How a retired household draws down the corpus determines whether it lasts 25 years or 15. The bucket strategy is the structure that works best in practice.

Bucket 1 — immediate (0 to 2 years of expenses).
Held in liquid funds or sweep-in FDs. Monthly household expenses are debited from here. The purpose: you never have to sell a market-exposed asset to pay next month's bills, so market swings don't force any action.

Bucket 2 — short-term (2 to 5 years of expenses).
Held in short-duration debt funds and arbitrage funds. Earns 6 to 7 percent, low volatility. Refills Bucket 1 as it depletes.

Bucket 3 — medium-term (5 to 10 years of expenses).
Held in balanced advantage or dynamic asset allocation funds. 40 to 60 percent equity, 40 to 60 percent debt. Earns 8 to 10 percent across cycles. Refills Bucket 2 every 2 to 3 years.

Bucket 4 — long-term (10+ years of expenses).
Held in equity mutual funds, largely large-cap and flexi-cap. Expected 10 to 12 percent CAGR. Never touched directly for monthly expenses. Refills Bucket 3 opportunistically after strong bull-market years.

The virtue of this structure: during a 25 percent market crash, nothing in Bucket 1 or 2 is affected, Bucket 3 is only moderately hit, and Bucket 4 (which is the biggest, but also the one not being drawn from) rides it out. The retired household's monthly cash flow is undisturbed. Three or four years later, when markets have recovered, Bucket 4 refills Bucket 3 at good levels. A complete market cycle happens, and the household never had to sell a share at a low.

Common retirement planning mistakes

Underestimating inflation. Planning based on current expenses, forgetting that Rs 1.5 lakh per month in 2026 will feel like Rs 4 lakh per month in 2044. Always compute in future rupees.

Treating EPF balance as "the retirement corpus." For most professionals EPF covers 20 to 30 percent of the total need. It is a foundation, not the full plan.

Not increasing SIPs. A flat Rs 50,000 SIP from age 35 to 55 is a different outcome from a Rs 50,000 SIP with 10 percent annual step-up. The second one is usually twice the first at the end.

Reducing equity too early. People start shifting into debt at age 45, "because retirement is only 15 years away." 15 years is a long equity horizon. The shift should begin around 55, not 45.

Ignoring health insurance. A Rs 15 lakh base + Rs 50 lakh super top-up health cover, maintained into retirement, protects the corpus from being wiped out by a single hospitalisation. More on this in our health insurance article.

When to start, when to review

Start the moment you have a salary. A 10,000 rupee SIP at age 25 beats a 50,000 rupee SIP at age 40 for the same end corpus. Time in the market, not amount of money, is the main driver.

Review once a year. Specifically check: are you still saving enough given your current expenses, has your target retirement age changed, has your EPF rate or NPS allocation drifted. If any of these moved materially, the required monthly investment changed too.

Retirement planning is not an event. It is 30 years of monthly SIPs plus one review a year. Done well, it is the quietest financial decision a professional makes — and the one with the biggest downstream impact on the last third of their life.
